- Copenhagen V, Denmark Filed Nov. 2, 1964, Ser. No. 408,426 Claimspriority, application Denmark, Nov. 2, 1963, 5,156/ 63 3 Claims. (Cl.40--334) This invention relates to writing implements andvmorespecically to a novel and improved writing instrument such as a pencilor fountain-pen or ball point pen having illustrations, the presence ofwhich is only suspected or guessed from the outer appearance of theinstrument.

One object of the invention resides in t-he provision of a novel andimproved writing implement having illustrations or display means orindicia hidden in its housing along its rear side, but neverthelessclearly visible when regarded through the rear end of the implement.

Another object of the invention resides in the provision of a novel andimproved writing implement including a reciprocable writing member, theillustrationsV being visible through the rear end of the implement andchanged or modified through the activation of the writing member.

The above and further objects and advantages of the invention willbecome more apparent from the following description and the accompanyingdrawings.

In the drawings:

: FIG. 1 is an elevational view of .a ball point writing instrument,embodying the invention, having a retractable writing member which isshown in its extended or writing position;

FIG. 2 is a sectional view of the ball point pen according to FIG. 1;-

FIG. 3 is a sectional view similar to FIG. 2 but with the writing memberin retracted position;

FIG. 4 is a dat layout View of a cylindrical element mounted in thewriting implement according to FIGS. 1-3;

FIG. 5 is a sectional View of a modified form of writing implementembodying the invention.

Referring to the drawings the embodiment according to FIGS. 1-4comprises a housing 1 having a forward part 2 with a tapered tip 3 and arear part 4 with a pocket clip 5.

Centrally in the housing is mounted a ball point writing member 6 havinga flattened portion 7.

A retraction spring 8 is placed in the -housing around the writingmember 6 between its iiattened portion 7 and a recess on the inner sideof the tapered tip 3.

A bushing 9 with screw threads 10 is fastened to the upper end of theforward part 2 of the housing.

The rear part 4 of the housing is at its lower part pronvided with aninwardly extending collar 11.

The rear part 4 of the housing is secured to the lower part 2 by meansof a cylindrical member 12 having an enlarged portion 13, the outsidediameter of which corresponds to the inside diameter of the rear part 4of the housing.

The lower part of the cylindrical member 12 is sealed in the upper partof the bushing 9.

The rear part of the housing thus is slidable along the bushing 9. Attheupper end of the bushing eight tapered teeth 14 are provided.

A cylindrical element 15 is sealed to the outside of the teeth 14.

The upper part 16 of this element comprises a translucent iilm with tworows of pictures, imprints or the like illustrations or indicia, thecenterlines of the lower and the upper row are indicated in FIG. 4 by c'and c", respectively.

,. YICC The lower part 17 of the element 15 comprises a cylinder havingon its inner surface two slightly projecting guides 18, diametricallypositioned.

Between the upper part 16 and the `lower part 17 an inwardly projectingring 19 is provided. Slidable in the direction of the axis of thehousing a hollow cartridge or socket 20 is inserted, having at its lowerpart four equidistant teeth 21, and having a top 22.

The top end of the writing member 6 is itted into the hollowness of thecartridge 20.

The top of the rear part 4 of the housing is closed by a hollowcylindrical plug 23. In the upper end of the plug a magniying lens 24 isinserted and in the lower end a 45 inclined mirror 25 is sealed. Thewall opposite the reiiecting surface of the mirror has been removed.

The position of the mirror is adjusted in such a way that the center ofthe mirror is in alignment with the centerline c' of the translucentfilm when the writing member is in writing position.

Between the plug23 and the uper end of the rear part 4 of the housing aring 5 carrying the pocket clip 5 is inserted.

Moreover, the plug is inserted in the rear part 4 of the housing in sucha position that the center of the mirror is aligned with the center of awindow 26, cutout in the rear part 4. l

To cover the gap between the forward part 2 and the rear part 4 of thehousing a belt ring 27 is fastened to the upper part of the bushing 9,just allowing the rear part 4 to be rotated or retracted.

When the writing member 6 is in the writing position shown in FIGS. land 2, the tive segments of the lower row of the film will successivelyappear between the window V26 and the mirror 25 when the rear part 4 isrotated. f 'v Even if the iigures or pictures appearing on the film areso small that their details are ditiicult to distinguish with the nakedeye, the picture appearing, when viewed through the lens 24, due tolight penetrating the segment of iilm in the window 26 shows easilydistinguishable details.

When the writing member is retracted to the position shown in FIG. 3,the rear part 4 is pressed downwards against the upper end of theforward part 2 of the housing. During this movement, the lower part ofthe teeth 21 engage the teeth 14 and thereby the cartridge 20 isslightly rotated. When the pressure on the rear part 4 is released, thespring 8 will force the writing member 6 and the cartridge 20 upwards.During this movement, two adjacent teeth will pass on each side of theguide 18 until their top ends contact the ring 19. Now the window 26will be in register with the upper row of the lilm and the illustrationsof this row will successively be visible through the lens 24 when therear part is rotated.

In order to extend the Writing member into writing position, the rearpart 4 is again pressed downwards, and the ring 19 forces the teeth 21downwards between the teeth 14. Thereby the cartridge 20 is againslightly rotated, and when the pressure on the rear part 4 is againreleased, two diametrically positioned teeth will each enter the gap 18'in the corresponding guide. The writing member will now be in theposition shown in FIGS. 1 and 2.

FIG. 5 shows a more simple embodiment of the invention. 106 is a writingmember secured to a cylindrical member 123, having a mirror 125. To thecylindrical member 123 a double-walled cap 104 is secured. Opposite themirror, parts of the walls have been removed in such a way that lightmay fall upon the mirror through a window 126 in the outer wall. In thetop of the cap a lens 124 is inserted. The cylindrical member 123 withthe writing member 106 is inserted in a housing comprising a forwardpart 102 secured through a screw thread in the groove 129, the lowerpart of the lm appears be-v hind the window 126, and when the cap 104 isrotated, successive segments of the lower part of the film appear andmay be viewed through the lens.

When the tap reaches the channel 131, the writing member may beretracted, and now the upper part of the lm 116 is illuminated throughthe window 126 and may be viewed through the lens during renewedrotation of the cap 104.

Other embodiments and modifications of this invention will suggestthemselves to those skilled in the art and all such of these as comewithin lche spirit of this invention are included within its scope asbest delined by the appended claims,
